The Xerox Phaser 7300 offers users an option to reduce printing costs by printing in-house memos and document drafts using the “toner saver” mode, while still producing legible documents. Four laser cartridges are provided with the Xerox Phaser 7300 including cyan, magenta, yellow and black toner powder. Each starter color laser cartridge has a duty cycle of 7,500 A4-size pages at 5 percent coverage, however, there are also high capacity laser cartridges available with duty cycles of up to 15,000 A4-size pages at 5 percent coverage. Users of the Xerox Phaser 7300 should consider renewing their own Phaser 7300 laser cartridges with our high capacity bottles of toner powder. One toner powder bottle yields one toner powder recharge and contains either black toner powder, cyan toner powder, magenta toner powder or yellow toner powder scientifically designed for use with this color laser printer, making renewing the laser cartridge fast and simple.
